TIRE-RIM.

Specification of Letters Patent,

Patented Au g. 1, .1.916.

Application filed July 26, 1915. Serial No. 41,998.

T 0 all whom t may concern Be it known that I, PnnoY W. BURroRD, acitizen of the United States, residing at East Rochester, in the countyof Monroe and State of New York, have invented new and usefulImprovements in Tire -Rims, of which the following is a specification.

This invention relates to tire rims and more particularly to that typeof rim which is removably mounted upon a vehicle wheel and adapted to bedetached and collapsed to facilitate the removal of the tire.

Heretofore, rims of this character have been constructed of hingedsections with free ends arranged to' be sprung past each other or tofold inwardly, but as these ends were not connected, there was noassurance of their assuming their proper relative position andmaintaining the same when the parts of the rim were held to the tire.

' The object of this invention, therefore, is to avoid this diliculty,and, broadly speaking, the device consists in providing a sectional rim,the sections of which are hinged together and the free ends connected insuch manner that 'when restored to operative tire holding position,their proper relative posi tion is always assured.

' Figvl. Fig. 6 is a lapsed.

Further objects ofthe invention will appearv as the following specificdescription is read in connectionwith the'acompanying drawing whichformsapart of this application, Aand in which Figure 1 is an elevationof the rim in operative tire holdingposition. Fig. 2 is a similar vie\vFig. 3 is a similar view with the rim fully collapsed and in positionfor the removal of the tire or replacement thereof. Fig. 4 is asection-on the line 4-4 of Fig. 1. Fig. 5 is a sectional view on thelline 5-5 of detail elevation showing a modified hinge connection.

ln the specific embodiment of the invention, the device comprises a pairof sections 1 and Z hingedly connected together as shown at 3 and havinga pair of short locking sections 4 andj connected to their freeterminals by means of the hinges 6 and 7.

1he locking section 4 has its free end beveled inwardly as shown at 8 tocorrespond with an outward with the rim partially col.

bevel 9 formed on the end of the section 5. 'These sections, as shown,are pivotal ly connected together by a link or links 10 which insuresthe proper relation of the parts and facilitates the collapsing of thesections and the forcing of the sections to operative tire holdingposition. When it is desired to remove the tire from the rim, thesection 5 is moved inwardly to the osition shown in Fig. 2 and then bethsecions 4 and 5 are moved inwardly to the position shown in Fig'. 3.yThe sections 1 and Q'are thus drawn toward each other which permits theready removal of the tire. The tire is placed upon the rim when inposition shown in Fig. 3 and the sections 1 and `2` then separated totheir fullest extent. The section 4 is pushed into position tocircumfcrentially aline with the sections 1 and 2 and the section 5 isforced' up so that its beveled end 9 engages and rides upon the beveledend 8 of the' sectiton 4. .'Wheh the rim is in this position, it may beplaced upon the wheel and secured in any suitable manner. v

What is claimed is z- 1. A rim comprising a pair of arcuate lscctions,hingedly connected together, a pair of locking sections adapted tocircumferentiallv aline with the first mentioned sections, hingesconnecting the locking' sections to the iii-st mentioned sections, and alink connecting the locking sections, said locking sections havingmating beveled ends.

2; A rim comprising a 4pair of arcuate sections hingedly connectedtogether, av pair of locking sections adapted lto circumferentiallyaline with the first mentionedjsection and each having alongitudin'allyextending slot between lits sides at one end, mating beveled faces, onthe slotted ends of the locking sections, andan arcuate link adapted tonormally lie within said slots andhaving its respective terminalspivotally connected with the locking sections between the ends thereofand below the beveled faces on said sections.

In testimony whereof l ailiX my signature in presence of two witnesses.
